PASE:
Pacific Atmospheric Sulfur Experiment

Summary

The Pacific Atmospheric Sulfur Experiment is a comprehensive study of the chemistry of sulfur in the remote marine troposphere. A major part of PASE will be devoted to the chemistry and physics (primarily of sulfur) in a cloud free convective boundary layer (CBL). During the first phase, PASE investigators will study the chemistry and physics of gases and aerosols in a cloud free environment. During Phase II, the PIs will focus on developing a better understanding of the formation of new particles in the cloud outflow of marine cumulus. PASE field activities will take place on Christmas Island in the Pacific Ocean from 2 August through 10 September 2007. The NSF/NCAR C-130 will carry the chemistry payload in support of the campaign.
